Format
------
CSV, comma separated, one header row:
    timestamp,open,high,low,close,volume

timestamp  US Eastern time (America/New_York, daylight saving applied),
           "YYYY-MM-DD HH:MM:SS". Each bar is stamped with the START of its
           interval: the 09:30:00 one-minute bar covers 09:30:00-09:30:59.
open/high/low/close  US dollars.
volume     shares traded during the bar.

Sessions   pre-market 04:00-09:30, regular 09:30-16:00, after-hours 16:00-20:00.
Gaps       a bar is written only when at least one trade printed in that
           interval. Minutes with no trades are omitted, never forward-filled.

5-minute and 1-hour bars are built from the 1-minute bars: open = first open,
high = max high, low = min low, close = last close, volume = sum. Bins are
clock-aligned (09:30, 09:35 ... / 09:00, 10:00 ...) and stamped with the bin
start. The 09:00 hourly bar therefore holds pre-market 09:00-09:29 and the
first 30 regular-session minutes.

Adjustment
----------
unadjusted  prices and volume exactly as traded.
adjusted    back-adjusted for splits and cash dividends as of 2026-10-10.
            Split ratio r on ex-date D: prices before D divided by r, volume
            multiplied by r. Cash dividend d on ex-date D: prices before D
            multiplied by (1 - d / C), where C is the regular-session close
            of the session before D. Factors compound backwards in time.
            Adjusted history changes whenever a new split or dividend goes ex.
